AI Thread Summary
The discussion revolves around the pricing of Radon, specifically the meaning of "$4/m." Initially, there was confusion about what "m" represented, with assumptions that it could be a unit of volume or mass. Upon further investigation, it was clarified that "m" likely refers to "mCi," or milli-Curie, a unit of radioactivity. The conversation also referenced multiple sources that provided varying details about Radon's pricing, including a mention of "$/100g." Ultimately, the clarification of "mCi" helped resolve the initial confusion regarding the pricing unit for Radon.

Radon price: $4/m ??

I'm doing some research on Radon. I have to put together a PowerPoint presentation that describes its origins, properties, characteristics, etc. (Each student was assigned a different element.)

One piece of information I'm required to report on is current price to purchase a sample of the element. I have found only one source that mentions a purchase price for Radon, and it says "Radon can be purchased for approximately $4/m." - without further explanation.

What is "m"?? I assume it must be a unit of volume or mass, but if so I'm not familiar with it.

Any ideas?

Mmmmm metre, that well known unit of mass... :smile:

Can we see the source?
 
Yes, of course! Sorry, I should have posted that.

The actual quote is "Radon is available at a cost of about $4/m."

edit: That same source has a table above the text which states that the cost is "$/100g" (no numeric value is given).

Hmmm... I just found another source that says: "Radon is available at a cost of about $4/m Ci."

I know that Ci is a Curie, measuring radioactivity. Could "m Ci" mean mCi: a milli-Curie?

edit: second source is http://www.speclab.com/elements/radon.htm

That would be right.

Woohoo! That makes a lot more sense than "m"!
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
